A method for editing an image on a display unit, an apparatus for executing the method and a computer program product for the method, wherein a predetermined CG object is designated in an image on the display unit, and in order to edit the image, a first command list for speech, motion, moving image reproduction or audio reproduction is displayed on the display unit, a command for editing the designated CG object is selected from the first command list and executed for the designated CG object. In the method of editing the image on the display screen and the apparatus for executing the method, the position information of the CG object located in the CG studio on the display unit and the information on the position and orientation of the camera for imaging the CG studio are read from a memory, it is determined whether the CG object selected by the pointing device is a CG character or a property, the information on the position to which the pointing icon has moved on the display unit by manipulating the pointing device is acquired, and the selected CG object is moved to the position to which the pointing icon has moved. Based on the information on the position to which the CG object has moved, the data on the character set-up window is updated in the case where the CG object is a CG character, and the data on the studio set-up window is updated in the case where the CG object is a property. The selected CG object can be dragged to the desired position by the pointing device.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of editing an image displayed on a display screen of a display unit, comprising the steps of: reading from a memory unit position information of computer graphics (CG) object located in the CG studio displayed on the display screen and information about position and orientation of a camera which picks up an image of said CG studio; acquiring the information about a position to which a pointing icon has moved on the display screen of said display unit by the operation of said pointing device; selecting a CG object on the display screen; determining a three-dimensional area surrounding the CG object in the CG studio; making coordinate transform on the three-dimensional area to a two-dimensional area on the display screen; in a case that the pointing icon is located within the two-dimensional area, determining that the CG obiect existing in the two-dimensional area has been selected; and moving the selected CG object to the position which said pointing icon has moved, wherein said step of moving the selected CG object comprises the step of: determining the plane on which said CG object moves in said CG studio based on said information about the position and orientation of said camera.
2. A method according to claim 1 , further comprising the step of: determining whether the CG object selected by said pointing device is a CG character of a property.
3. A method according to claim 2 , further comprising the step of: updating data of a character set-up window on the display screen in the case where said CG object is a CG character; and updating data of a studio set-up window on the display screen in the case where said CG object is a property, based on the information on the position to which said CG object has moved.
4. An apparatus for editing an image displayed on a display screen of a display unit, comprising: means for reading from a memory unit position information of a computer graphics (CG) object located in a CG studio displayed on the display screen and information about position and orientation of a camera which picks up an image of said CG studio; means for acquiring the information about a position to which a pointing icon has moved on said display screen by an operation of said point device; means for determining a three-dimensional area surrounding the CG object in the CG studio; means for making coordinate transform on the three-dimensional area to a two-dimensional area on the display screen; means for determining that the CG obiect existing in the two-dimensional area has been selected in a case that the pointing icon is located within the two-dimensional area; means for moving a selected CG object on the display screen to said position to which said pointing icon has moved; and means for updating data of a character set-up window on the display screen in the case where said CG object is a CG character, and updating data of a studio set-up window on the display screen in the case where said CG object is a property, based on the information on the position to which said CG object has moved.
5. An apparatus according to claim 4 , further comprising: means for determining whether the CG object selected by the point device is a CG character or a property.
